That little slice of heaven between a broad's legs. Contrary to popular belief the broad does not have to have deplorable hygiene or actually stink like low tide to refer to her snatch as the stinky pink.
When a women get's fucked by three guys at once: one's in her ass (the Stink), another's in her pussy (the Pink) and the third's in her mouth (the Drink).
Rick: Man, I ass-fucked that high school slut last night!
Ron: She's 15, right?
Rick: No, she's 13, but MAN was that bunghole tight!
Ron: Jesus Christ, Rick.
Rick: I LOVE the Stinky Pink Pickle!
